If you are new to online shopping. This is a good place to begin. It is clear by his name " buy.com". What you can buy from here? I will prefer in electronic items. The first, they have good deal in lot of electronic items, and computers. Not just good deal, but also have cheap shipping fee. Most important is they have competition deal to other major deal site like "tigerdirect". So if you look something cheap, buy.com may be the one the list.
Talk about the online shopping, the safety is the major issue to new guy. I shop from buy.com for 4 years. All money transfer are clear and all recorder are in my account no missing. You can know when you buy it and when your item will expire on warrant.
Buy.com have all kinds of payment methods. One of the feature is google check out. If you have google account, you can save $10 for your first time check out. BTW, every google account can have one discount. It mean if you have more than one you will have more than one chance to get $10 off.
They also have refurbish item sale. It is always good deal for electronic items. Also they have a lot mail in rebate items, too. Plus with free shipping. All I will say is " It is a good place to looking for nice deal."
